Shaco demands high game knowledge and proficiency; practice extensively in normal games to master jungle pathing and macro before playing ranked.
Avoid overcommitting to early counter-jungling without managing your own resources; focus on calculated plays to translate early leads into late-game teamfight impact.
As Shaco Support, refrain from blindly abandoning your ADC. Instead, focus on impactful roams and strategic picks to truly contribute to the game.
